Why is UPnP browsing so terribly slow?

Question

Hi, I was using your API for browsing media servers, I mean via KnownFolders::MediaServerDevices , but I had to rewrite it to use our SOAP requests, because it was terribly slow when browsing containers with more than 200 items. e.g. 400 items taken almost 1 minute!

Even if I wanted to get just 10 items like this:

GetFoldersAsync( CommonFolderQuery::DefaultQuery, 0, 10)

it still takes 1 minute for a container with 400 items while it takes just a second using Windows Explorer or by using my SOAP browser.

Are you going to fix it or I need to continue to use my own implementation?

Answer 4

Doesn't look like we ever got any more information about how to repro.  Do you have a project and repro steps you can post to OneDrive?
